It doesn't need to be a linear correlation, but there should be some correlation between worker productivity (aka produced value per hour of labour) vs wages. It hasn't happened, at all [1]. And that's ridiculous, workers are much more productive while real wages have stagnated when inflation is taken into account.

> When it comes to the pace of annual pay increases, the top 1% wage grew 138% since 1979, while wages for the bottom 90% grew 15%

> Middle-class wages are stagnant—Middle-wage workers' hourly wage is up 6% since 1979, low-wage workers' wages are down 5%, while those with very high wages saw a 41% increase
